A sector of a circle has a central angle of 45 . Find the area of the sector if the radius of the circle is 15 cm.

prohojiy [21]

Answer:

A = 28.125 * pi cm^2

A = 88.357 cm^2

Step-by-step explanation:

Area of a sector is 1/2 r^2 theta where theta is in radians

convert 45 degrees to radians

theta = 45 * pi/180 = pi/4

A = 1/2 * 15^2 * pi/4

A =1/2 * 225 * pi/4

A = 28.125 * pi cm^2

A = 88.357 cm^2

I need some help with this calculus question

Over [174]

The tangent to $y$ at the point (0, 5) has a slope equal to the derivative evaluated at $x=0$ .

$y=x^4+5e^x\implies y'=4x^3+5e^x\implies y'(0)=5$

This tangent passes through the point (0, 5), so its equation is

$y-5=5(x-0)\implies y=5x+5$

The normal line passes through the same point, but is perpendicular to the tangent line, so its slope is the negative reciprocal of the slope of the tangent. So the equation for the normal line is

$y-5=-\dfrac15(x-0)\implies y=5-\dfrac x5$
